TEMPORARY BINDER.

Specification of Letters Patent.

Patented May 8, 1906.

To all whom it may concern:

Be it known that I, CHRISTIAN Knox, a citizen of the United States, residing at Orescent Springs, in the county of Kenton and State of Kentucky, have invented certain new and useful Improvements in Temporary Binders, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates to that class of binding-files or loose-leaf binders which are now generally known to the trade as post-binders, wherein any convenient number of letters, bills, or other sheets are held until they are readyto be permanently bound up or filed away.

These binders usually consist, as in the present instance, of a base-piece from which extend at right angles thereto and near the top edge thereof two filing-rods upon which the leaves or other papers to be filed are strung and which are secured in place by a sliding top piece or follower, usually in the form of a hinged book-cover, and provided with means for locking the same to the filingrods when pressed down upon the leaves and for unlocking the same to permit it to be raised and removed from the rods to introduce new leaves or change their relative positions on the rods; and it has for its object the production of a binder of this class which is cheap and simple in its construction and exceedingly efficient in action and in which the binding member is so slotted that it can be slipped bodily from the rods without having to be slid up over their tops and can be replaced in the same manner and then be clamped to the rod, all as will be hereinafter more fully set forth, and specifically pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a binder embodying my invention and with one of the posts partly broken off. Fig. 2 is a detail sectional elevation through the upper end of the binder on the line of one of the posts and with the binding-clamp removed. Figs 3 is an enlarged perspective View of the box or housing of the binding-clamp. Fig. 4 is a perspective view of the top clamping-plate. Fig. 5 is a corresponding view of the bottom clamping-plate.

to form an offset or shoulder 13. 1 end of the slide 9 has a slot 14 for the passage Fig. 6 is a corresponding view of the baseplate. Fig. 7 is a perspective view of the operating-lever. Fig. 8 is a detail plan view showing the position of the parts when the operating-lever is so turned as to cause the clamping-plates to bind or pinch upon the posts. Fig. 9 is a corresponding view at one end of the clamping-plates, showing a post clamped or pinched between them.

The same numerals of reference are used to indicate identical parts in all the figures. As is customary in this class of binders, 1 is the back or base,- to which is flexibly secured at its upper edge a metal strip 2, into which the lower ends of two binding-posts 3,

which are parallel to each other and at right angles to the metal strip, have their lower ends secured by riveting or by being screwed thereto, as seen in Fig. 2. The papers to be bound have their upper ends perforated to slip over the posts 3, and a cover 4, having a hinged upper extension 5, with slots 6 through it to slip over the posts, rests on the top of the papers, as seen in Figs. 1 and 2. These papers may be letters, bill-heads, ordersheets, or, in fact, any kind of papers that it is desired to file in a temporary binder and afterward when the binder is full to remove the same to a permanent hinder or transfercase.

By providing the slots 6 in the upper edge of the cover 5 it may be drawn down off of the posts without having to be slid up and lifted off of them when it is desired to add papers to or removethem from the file.

It is necessary in a file of this character, especially Where the top cover is slotted and slipped off of the posts and a large number of papers are to be filed, that there should be clamping mechanism of some sort to grip the posts and hold the top cover securely down upon the papers, and I have provided avery simple and efficient clamping mechanism for this purpose, which consists of a base-piece 7, Fig. 6, united in any suitable manner to the piece 5 and with slots 8 in its upper edge, and

1 on this base-piece 7 are mounted two slides 9 s and 10, Figs. 5 and 4, respectively, each having a central opening 11 and 12, respectively, the opening 12 having one end stamped down The one of a screw 15, Fig. 1, which unites one end of a housing or covering-box 16, which incloses the slides, to the base-piece 7. Adjacent to the slot 14 on the upper edge of the slide 9 is a slot or opening 17, one side of which is ogeeshaped, as seen at 18, while on its opposite or lower edge at the opposite end is a cut-out portion or opening 19, from which point the slide is bent upward and then parallel with itself, as seen, and at this end there is a projecting tongue 20, terminating at its inner edge with an ogee curve 21.

The slide 10 has its ends reversely shaped to the slide 9that is, the tongue 22 and ogee curve 23 are over the slotted portion 14 and opening 17, While the opposite end of said slide has its slot 24, ogee curve 25, and opening 26 under the tongue and ogee curve 21, thus permitting the two slides to become partially interlocked while resting directly the one upon the other and with the ogee curves opposed to each other and in line with the posts 3, as clearly indicated in Fig. 9.

A struck-up sheet-metal box 16 covers theslides snugly and is secured to the base 7 by the screw 15, before mentioned, which passes without binding through the slot 14, and by a similar screw 28, Fig. 1, which passes in a similar manner at the opposite end of the box through the slot 24, while the tongues 20 and 22 pass on each side of the screws. It will thus be seen that the two slides are interlocked and have slight endwise movement u on each other within the housing 16, and t e housing is likewise provided at its upper edge with slots 29, registering with the slots 8 and 6 in the base-piece 7 and iece 5 and also with the openings formed by t e ogee curves.

Without any further mechanism the cover 4 could he slipped back and forth upon the posts without any pinching or binding efiect to lock the plates to the post, and to accomplish this I provide the cam-lever or thumbpiece 30, Fig. 7, which has a portion 31 on its under side projecting downward and with rounded edges and from which, on its upper and lower sides at the middle, extend pintles or trunnions 32, confined in bearing-apertures 33 34 in the top of the housing and in the baseiece 7, respectively. The handle of the cam t umb iece or lever extends through a slot 35 in t e inner edge of the housing 16, while the cam projection 31 is confined in the openings 11 and 12 of the slides 9 and 10, respectively, as seen in Fig. 8. The pressing of this lever in one directionnamely, that shown in Figs. 1 and 8spreads apart the slides, so that they pinch or bind upon the posts 3, as seen in Fig. 9, while upon turning the thumb-piece to the opposite side, so that the projection 31 stands transversely to the slides or at right angles to the position shown in Fig. 8, the slides are released and will spread apart to unclamp the posts 3 and permit the cover 4 to be drawn bodily oil of the posts or to be slid up upon the same, as will be readily understood.

While I have shown a separate base-piece 7 for the slides and housing, it is evident that such base-piece may be dispensed with if the portion 5 of the cover be made of metal and the slides and housing rest and be secured directly thereon. Again, whileiI prefer the use of a hinged cover 4, attached to the clamping mechanism, the same may be dispensed with and the clamping mechanism alone may be employed, as will be readily understood. It is also to be observed that when the cam projection 31 is spreading the slides to lock them to the posts it forms a practical toggle which will not become accidentally disengaged, but will require pressure upon the handle 30 to break the togglejoint. Again, it is to be observed that the ogee curves upon the slides are simply gripping-jaws for gripping the slides upon the posts and releasing them therefrom, and while I have shown them and described them as ogee curves any other shape for the gripping-jaws which would accomplish the same result would answer as Well and come Within my invention.

Having thus fully described my invention, I claim- 1. In a temporary hinder, the combination of a bottom filing-base, a pair of filing-posts extending therefrom at right angles thereto and parallel to each other, a clamping-piece with slots in its upper edge registering with the binding-posts, slides upon said clampingpiece provided with gripping-jaws registering with said slots, a housing for said slides covering the same secured to the clampingpiece and provided on its upper side with slots registering with the slots 1n the clamping-piece, and a camiece, whose cam is confined in openings in t e slides with a projecting portion by which it can be vibrated and whereby when turned in one direction it causes the gripping-jaws of the slides to bind upon the posts, substantially as described.
